Tandem Trikes & Other Favourites

John and Jane Moss have taken the difficult decision to sell their Tandem trike, owned by them since 7^th July 1979. Well, back in 1979, it was a Peugeot touring tandem, and rebuilt as a trike, back in 2007. https://www.sevendaycyclist.com/love-resurrection-john-moss-s-tandem  

Much money has been spent upgrading the drivetrain and braking. End of an era. However, John’s trike focus, has turned almost exclusively to his Sinner Mango Velomobile. Sadly, there’s no longer enough room, in his workshop, for both. Contact me, by email, if you are interested in buying their tandem trike. 

Elsewhere, I’ve relocated “Franenpute” sensor and magnet, to chainstay and rear wheel. This appears to have solved the interference hassles, when SP PD8 and SL9 dynohubs https://www.sevendaycyclist.com/halo-evura-shutter-precision-sl9-dy  are switched on.

500 miles in, and I’ve also warmed to the Passport Element Chain. At 802 kg, tensile strength is noticeably lower than track type fare, such as KMC Z1 inox https://www.sevendaycyclist.com/kmc-inox-chain (1050kg). These are almost twice the Passport’s asking price, so direct comparisons are unfair.

I’m 70 kilos, so don’t tax components in the same way a powerfully built, 90kilo rider will. Though I noticed the difference in tensile strength, when powering along a climb. I’d be happy popping one on a traditional winter/fixed conversion, single speed freewheels; or hub geared road build.  

More powerful riders, or those living in hillier regions and who only run a single, front brake, would be better served by something like the KMC. Nonetheless, true to claims, lubricant clings to the rougher, galvanised texture.

This not only means it stays put but there’s less clean up, and transference to hands/clothing.  I’ve had to tweak tension, on a couple of occasion, most recently this week, by the roadside.

For one, moral sapping moment, my beloved and long serving Pedros Trixie multitool seemed elusive. Thankfully, the 15mm head popped out from behind a tightly bound spare tube.

Back in September, the fixed hub belonging to the Mavic Open Pro build expired. I’d switched to the Halo Aerorage but pondered what to replace the Mavic’s no-name hub with. I’ve had no problems with cheap hubs in the past. An On-One Inbred unit served a good twelve years before expiry.

A simple cup n’ cone Maillard double fixed unit, graced my first fixed gear build, which was based around a 501 Raleigh frameset. The Inbred is a better bet, for daily drivers cum hack bikes, courtesy of sealed bearings and perfect for a utilitarian build. The sort which needs to be reliable but not attract unwanted attention, when locked to street furniture for longer periods.

Then this Halo rear fix G track hub, was offered me by Ison Distribution https://www.ison-distribution.com/english/product.php?part=HUHATG2K . Sealed bearings and hollow Cro-moly axles bode well for year-round/winter service. Look closely and you’ll notice a HG cassette type assembly for loading fixed sprockets.

Aside from the obvious convenience-no need for medieval looking chain whips, this allows for an adjustable chain-line, between 41and 52mm. Theoretically, a boon for older road conversions. However, those looking to leave their frame spacing untouched may find Surly New Road Rear https://www.ison-distribution.com/english/product.php?part=HUSURRDK a better option.

Don’t be tempted to use HG cassette sprockets with the rear fix G. Stick with 7mm Halo Fat foot, or Gusset Double Six sprockets.

Then there’s an independent lock-ring, that doesn’t have to deal with those rotational forces, traditionally synonymous with fixed transmissions. Talking of which, it will also entertain fixed sprockets between 12 and 20teeth. This should cater for pretty much every occasion, including fixed gear cross/gravel antics.    

Tioga City Slickers are another definite favourite of mine and 25 years later, they’re much as I recall, save for a new, “Energetic” 60tpi casing. Our samples are 700x32 but there’s a 38mm option, and plenty to please those of us, still running 26inch wheels.

I spent several years bombing round the capital on 26x1.95s, which were quick and compliant. Literally gliding over holes and lumpy ironworks. Punctures were rare events too. Or is that nostalgia weaving its hypnotic spell. Several weeks and a few hundred miles will tell.

One way, or the other.  Right, better glue this nasty looking (though thankfully, superficial) cut in the Soma Supple Vitesse EX casing. https://www.sevendaycyclist.com/soma-fabrications-vitesse  Before it expands, or a thorn, glass, or similar sharp sneaks inside.

Wild Horses

Several weeks and a few hundred mixed terrain miles later, I’ve reached some definite conclusions about the Revolution Cross 2 http://www.sevendaycyclist.com/revolution-cross-2.

It’s been a very welcome guest and we’re inviting other brands to send us their ‘genre blurring models to see how they compare in similar contexts. Raleigh has said they will be putting their £650 Maverick forward. http://www.raleigh.co.uk/ProductType/ProductRange/Product/Default.aspx?pc=1&pt=14&pg=15774

Sharing the Claris drivetrain (albeit 2x8) and Tektro Spyre brakes, its’ based around a 6061 aluminium frame and carbon fork and reckoned to weigh 2 kilos less-looking forward to swinging my leg over the 56cm’s top tube. 

Back on my blue/grey ‘cross inspired fixer, it’s been reminding me of what I've been missing, especially on the climbs.

For now the Avid BB7 and Cane Creek lever combo are delivering decent modulation and feel, although I’m still very tempted by the Spyre...Elsewhere, I’ve swapped its Time pedals over to the Holdsworth in exchange for the blue Issi and replaced the Ilpompino’s KMC Z1X chain, like for like, which also succeeded in killing three long serving chain tools!

Over three years hell n’ high water service hence; my Shimano R82 sports touring/Audax shoes are beginning to look decidedly peaky in places, so I’ve resurrected these very impressive Quoc Pham. A contemporary take on the classic touring shoe, the upper is made from high quality cowhide with lace lock lace system and 3M reflective heel strip.

This takes a while to break in but aided by a periodic lick of hide food, moulds beautifully to the foot. The outer sole is moulded rubber and features a hardened mid section and an unusually aggressive, SPD sole for improved grip. Power transfer isn’t quite on par with super stiff race slippers perhaps but it’s still very good. Craftsmanship and more importantly, long distance riding comfort is superb.

       

I went clipless back in 1992 with some Look ARC and patent leather Diavolo shoes (£50 all in from a local bike shop) but testing aside, my preference lies with the recessed SPD/R types. Discovered during my mud biased mid 90s, their sheer convenience is hard to beat.

Fixed, I can click in without needing to coax the pedal body into position, wet slimy decking aside, there’s little chance of me going down like the proverbial sack of spuds when its a bit slippery, or gouging holes in expensive lino.    

With autumn just around the corner, we’re beginning our lighting group tests. There’s the odd master blaster involved but otherwise, rather like megapixels, its more about the quality of lens and diodes, rather than firepower per se.

Models with several settings ranging from 800 down to 100/flashing modes cater for pretty much everything you’d need for the darkest rural roads through to well-lit city centres.

In the past I’ve been curious and even indulged in the 1,000 plus models offered on auction sites but while bright, they’re just too aggressive and beam quality/useable light doesn’t match that of those boasting 600 or so. In top mode, they can simply dazzle other road users-potentially dangerous, not to mention, extremely aggravating.

That said; I’ve used some budget (sub £100 CE compliant) official imports to excellent effect and the lower, steady settings can return 3-4 hours before kicking into flashing/SOS to conserve juice. Battery packs have become increasingly compact, riding unobtrusively beneath the top tube, rather than consuming a bottle cage.    

For those who don’t want, or need this additional clutter, tuneable torch types can be ideal for middle distance commuting and training but consider run-times carefully, if you’re tackling long stretches of unlit road. Several offer 600-800 lumens but there’s usually a serious trade off where run times are concerned-expect an hour or so, tops. However, they can strike just the right balance for those who generally ride in sub/urban contexts but want to indulge in some back road scratching after work.

Those with 300-400 lumens and several settings are surprisingly useful too, my choice for late summer evenings, where time can slip away and dusk set in unexpectedly. Blinkies are arguably all that’s required for getting home with in these contexts but I still prefer a proper light up front, blinkies acting as backing singers-especially given the all too prevalent culture of victim blaming-litigious, or otherwise.   

There is an increasingly popular trend for combining products-Cycliq fly 6 LED with integral camera being an excellent example. Along with Moon’s surprisingly potent Gemini, Raleigh has sent us this Icon + unit, which tailors light automatically to suit conditions.

http://www.raleigh.co.uk/ProductType/ProductRange/Product/Default.aspx?pc=2&pt=117&pg=18570

It’s capable of producing 190 lumens and even features a movement sensor, triggering an alert to your smart phone, indicating that your bike is being moved and potentially vandalised/stolen. Useful additional security when supping coffee and sharing ideas at a cafe’ stop; on that note, I’m going to see if this stuff is a creative kick start or belongs behind the creosote...

Good Housekeeping

Prevention is always better than cure, although the latter sometimes serves as timely reminder. After several rides in Monsoon conditions, a tell-tale gritty rasping when braking confirmed the Ilpompino needed more than superficial cat lick.

Consistently mild temperatures has seen my home brewed corrosion preserve continue to ooze from the bottom bracket shell, resulting in a sticky mess adorning the System EX cranksets’ inner spider and ring.

Staying on this subject a mo, I’m increasing impressed with Pro Gold Steel Frame protector, which seemingly leaches into the host metal in a similar fashion to J.P. WEIGLE’s legendary “framesaver”.These properties theoretically offer the most comprehensive protection, especially to painfully thin steels such as 531c. 

Using different blends of lubricant leads me to suggest while phenomenally corrosin resistant the KMC X1’s slippery stainless steel construction actively encourages migration from its inner rollers to outer plates and hub cones, thus compounding said gooey syndrome. This song remains consistent across the board, whether fortified with PTFE, two-part synthetic or various weights derived from vegetable stock.

Many standard bike washes are too insipid and their concentrates too harsh for tackling this sort of accumulated filth, especially on carbon/composites and similarly delicate finishes. 

Given this backdrop, I was surprised at just how effective Fenwick’s FS1 is.Regular readers will be aware that traditional types can prove quite hostile to humanoid operative and recipients alike.  However, while understandably tight lipped about precise chemistry, Fenwick’s tell me their biodegradable, solvent free blend is so mild, some mechanics use it as hand cleanser.

Just the same and without being unduly alarmist, I’m inclined to don latex examination gloves or at least minimise contact with anything of this ilk, given the experiences of friends and forbearers within manufacturing.

With this in mind, I decanted 50% concentrate into a little pump spray receptacle, diluting it with fresh water, sourced from my rain butt. Prince Buster was right; if you have your brush you can avoid the rush. Several blasts and three minutes standing time hence, tyre and rim sidewalls were truly ship-shape.       


Ever since the storms of October 1987, UK forecasters have been presenting the worse- case scenarios. Some suggested the tail end of Hurricane Gonzalo would herald early snow. It’s certainly been blowy and I’ve been grateful for the Univega’s dependable handling and moderate to low gear ratios, though I’ll postpone fitment of Schwalbe Winter tyres for a while yet. Handlebars and other contact points/accessories have been sprouting a fresh batch of blinkies.

There’s more than passing similarities between this Lucas, One 23 Atom and RSP Spectre enticing suggestion that these are the same unit but with different badges. Indeed, give or take a minute or two, they charge in the same timescales, produce 40 surprisingly potent lumens apiece and all integrate lens and switch for “sausage-finger” convenience.

Arguably a modern take on the bobby-dodger, there’s a steady trickle of “bridge” models filling the gap between these and traditional commuter lamps surprisingly well, reclaiming a whole heap of handlebar into the bargain.     

Boasting 300lumens each, Knog Blinder Road 3 and One23 have saved my bacon on several occasions-when I’ve been gassing with friends on summer evenings, or uncharacteristically nonchalant when charging big guns. However, running them at top whack quickly exhausts their lithium polymer cells-hardly ideal for use as primary lighting for commuting or training.


Not that it has stopped some sycophantic sorts rehashing press releases to the point where they’d have us believe this genre are genuinely powerful enough for warp-speed trail duties!  On that note, Muc-Off has sent me this X-3 dirty chain machine to play with, so I’m going on a virtuous purge of the fleet, introducing some super stubborn prep before November’s knock becomes louder.           

Lateral Thinking & A Saunter Through The Spares Bin

Bank holidays are a great opportunity to relax, reflect and therefore be more productive as a consequence. That said; self-employment in any capacity/context requires long hours, forward planning and oodles of self- motivation- I’ve seldom seen bed before 1am these past few months. Presently I’m working on my collaboration and specifically cover designs, which is a different but extremely rewarding challenge with intense flashes of inspiration.

Further investigation revealed the Ilpompino’s GXP cranks and cups had become sitting tenants, though three timely blasts of penetrant spray and gentle persuasion from this ACOR wrench accelerated a tidy eviction.

Obviously closed cup pro grade designs hold the winning cards when it comes to absolute precision, though open type enable loosening of the non-drive side, facilitating release of reticent two-piece Truvativ without recourse to more forceful techniques.

Much to my surprise, several salt strewn winters had infiltrated the chain-ring bolts, leaving their threads unexpectedly brittle. Hence I’ve introduced an understated but worthy sealed square taper bottom bracket and low mileage Stronglight 55 crankset for the short to medium term until such time the latter’s non-detachable ring becomes bin fodder, or I acquire something more glamorous.

110mm long axles might sound another curious choice for fixed gear builds but the chain line’s bang-on, those extra few millimetres breathing space prevents arms fouling cadence sensors and similar electrical gizmos.

Dropping a couple of teeth has lowered the gearing slightly (from 81 to 77.6 inches), lessening joint strain on more intense climbs and improving acceleration without hampering cruising tempo or inducing quasi comedic spin-out during long descents.

Such moments had me thinking about chain life. Derailleur set ups ascend the stairway to heaven between 800 and 1100 miles depending on rider sensitivity, standards of maintenance, lube and riding conditions but things seem considerably less prescriptive with single speeds. Obviously the former variables, not to mention chainline are significant players.

However, theoretically at least (given the additional loading associated with braking, track standing and explosive acceleration) one would reasonably expect this to be level pegging with their variable cousins.

I’ve had a brown 3/32 Sedis expire somewhat fatally nigh on 25 years ago while hurtling along at 42mph, inducing unwelcome mirth and interesting rider antics. Aside from last year’s infamous crush injury, there’s never been a spiteful moment or sense of impending expiry using 1/8^th track fare. 

The Ilpompino's  KMC is starting to shed its purple finish in places and I keep a generous length of links lest disaster strike miles from home but we’re well into three thousand miles. My preference is for half-links since they allow more precise pruning, especially on conversions where tensioning can prove tricky (vertical dropouts being a case in point) and some whisper 10,000 miles plus is readily attainable.

Galvanised coatings according to others are show-stopping must-haves, particularly but while taint resistance is pretty good, those I’ve used have lacked finesse unless fed a wet lube diet and eventually the zinc layer flakes away, leaving links exposed and therefore equally vulnerable to Joe n’ Joanna rot. Perhaps Inox is the answer to these particular prayers…
